True to life colour

Incorporating colour processing technology, the Optoma S321 brings realistic colours to life with a high contrast look. Bringing new depth to every image with brighter whites and rich black tones, text appears crisp, images look great and films come to life.

Designed to ensure your film, presentation or display looks great at any time during the day or night, the S321 features sRGB technology for accurate colour reproduction.

Energy saving features

Designed to reduce power consumption without sacrificing on quality, the S321 has an improved lamp life and energy saving features. Reducing maintenance and lowering the total cost of ownership, the specially designed lamp modes allow you to save up to 70% of power. With a long lamp life, the S321 can last for up to 10,000 hours without needing a bulb change.

Helpful features

To help save energy, Auto Power Off automatically turns the projector off if it's left running for too long without use. And when you need it again, Quick Resume lets you instantly power back up.

For any presentation or film, the projector connects easily to a PC or laptop. The lightweight design is perfect for easy installation or for taking out to off-site meetings.

Don't forget your accessories

Ensure your presentation looks its best with our range of projector screens, so that any room can be turned into a meeting space. The Optoma range spans up to a huge 92”, so that you can present talks, speeches and more to rooms of any size.
